Description of problem: User is not allowed to open Edit window and set in one transaction the following: configure vCPUs (in system tab), then pin to host in 'Host' tab and then resize policy in 'Resource Allocation' tab. Version-Release number of selected component (if applicable): ovirt-engine-4.5.0.2-0.7.el8ev.noarch How reproducible: 100% Steps to Reproduce: 1. Create VM on the base of the latest infra template. 2. Open Edit window and set the following: - 4 CPUs (Total Virtual CPUs system tab); - pin to specific host in 'Host' tab; - set resize policy in 'Resource Allocation' tab. - OK in the Edit window. Actual results: Error: Cannot edit VM. The VM NUMA configuration cannot be applied when using the CPU Pinning policy 'Resize and Pin NUMA'. The user only could do this by configuring vCPUs + pint to host, then OK in Edit window. Then Reopen and set the policy Expected results: Must be allowed by one transaction
Yes, I agree, that is not user friendly.
Please note that setting the vCPUs number (or modification of NUMA) is still not allowed, because it will be automatically set by the Resize and Pin NUMA Cpu Pinning Policy. However, a new UI warning will be displayed that allows to reset the changed values and continue with saving of the VM.
verified on ovirt-engine-4.5.1.2-0.11.el8ev.noarch according to the described scenario. the configuration is allowed in one transaction
